Smart Bmeters WaterMeter

thingiverse

A simple addition to the GSD8 water meter, which allows you to count pulses every 100ml of water, which translates into excellent measurement accuracy. The device consists of an adapter attached to the water meter (three tabs lock on the water meter) and a second element to which an M12 inductive sensor is attached. The two-element structure allows for printing without supports. Principle of operation: The water meter has a metal plate on the dial, which covers 50% of the surface. As it rotates, it alternately covers and discovers an inductive sensor that sends pulses to its output. 1 pulse = 100ml of water It is enough to connect the output to a module (e.g. ESP8266, ESP32 or something from ZigBee) to have a remote reading of the meter. The model of my sensor is LR12XBN08DPOY-E2, but any other in the size M12 and the operating range of about 5mm will be fine.
